IMO you buy art because you love it not because it “goes “ with the decor. I think one of the giant floral wallpapers would be great on that wall. BTW wood slat blinds and that chandelier do not work together

The bed frame seems more Beaux Arts to me. Perhaps something like this in place of the travel poster. https://www.greatbigcanvas.com/view/lermitage,1993348/ And a set of small vintage frames on the window wall next to the bed.

Hi. Design needs to happen in a logical order. So, I recommend prior to decorating that wall, you 1) Create a good floor plan. This one is not the best. I can help you with that if you tell me what the function of this space is and if there is a tv in the room. Finally, is this furniture staying in the room? Please post a photo of all 4 walls of the room, Thanks. 2) Find photos of rooms you like. What design/style do you like? Once you have those, we can then think about decorating the wall.

I'm shocked by the first post. Not because I don't know the interet is like this but you have a lovely room already and its very inviting. Could you go for something like this in the dining room? I'd add a tall tree to one side -- or maybe frame it with two! As for the entry area, I'd rethink it to be more functional because most people really do need that space to put down stuff or keep stuff. That doesn't mean constant clutter. But it's okay if it's empty and maybe just has an attractive bowl or catchall or tray on one side. Actually Levenger's sells a note "bleacher" where you can leave notes, letters you shouldn't forget to mail or mix in a favorite photo or postcards. https://www.levenger.com/products/note-card-bleachers?variant=42555135787157 I would also want some kind of umbrella holder under the console. I'd put a walking stick in there too but I like to use them. But I wouldn't put flowers or books or candles. (I might go for a great flaslight!) https://www.ebay.com/itm/195840629086?chn=ps&mkevt=1&mkcid=28&srsltid=ASuE1wT9G_7DHE4jqL58TaDePa2o8aNCXVHxJfYglXtvAachZnUY5M80qI8
